86 ERYTHEA. 



probable that many specimens in herbaria under the latter name 

 will be found really to belong in this species. Both occur through- 

 out the intra-montane region. In San Bernardino and Riverside 

 Counties A. fatua is the more common, but in many parts of San 

 Diego County (Santa Ysabel, Julian, Pensaquitas Ranch, Poway, 

 etc.) A. barbata is much the more abundant^ and often over 

 large areas the exclusive species. In the field the two species 

 may be easily recognized at sight. A. barbata is tall (1—8 ft.), 

 slender, fiexuous, green, with a diffuse open panicle, and slender, 

 pointed florets. A. fatua is stouter, glaucous, more rigid, and 

 has a usually smaller and more compact panicle, and broader 

 and blunter florets. 



Avena fatua glabrescens Coss. This does not differ in 

 aspect from the species, so that it may easily be mistaken for it, 

 unless the florets are examined, when they will be found to be 

 clothed with hairs only on the rachilla and at the base of the 

 flowering glumes. The variety is probably widely distributed, but 

 I have specimens only from Nordhoff, F. W. Hubby, and of my 

 own collecting at San Bernardino.
